things I learned from this article:

1. black noise exists
2. black noise models the frequency of natural disasters

welp, didn't want to sleep tonight anyway

Sorry it's been a couple days, but thanks again for all the links. And yeah I'd like to go the DIY route and build something. That zorlon cannon looks amazing though...

An "8bit" noise generator is basically a sample+hold. It switches the waveform between two different states (like -1, +1) according to an LFSR. But you could just generate the bits randomly, or select them yourself.

The sense of sweeping pitch is created by clocking the "noise function" (usually lfsr) faster or slower. If the noise pattern is very short it will sound like a pitched instrument, otherwise it will just sound like crispy noise at diff. pitches.

There must be an arduino proj that just does noise like this. Not really sure what op is wanting tho eg. hardware or software.

Well what you got there is a noisey bibblewatzit, not to be confused with the double inverted quazzle

pink and brown noise are specific types of noise relating to different mathematical functions, iirc.

That's all semantics, the sentence is correct either way. Get over it. :3

Might not be 100% LFSR only related but I will release my SN76489 (sega master system version) Vsti extended emulation in September...
The Super Portable Sound Generator aka Supa PSG.
One of the feature is the ability to tweak the noise channel
More technically you will be able to change the 16bit LFSR configuration in real time.
Changing the tapped bits and the feedback bit input can make the noise more or less tonal like switching between SN79489, Atari2600 etc..Noise types

that type of sound you give in your example is totally achievable.
Worth mentioning that the master clock of the system is not particularly tied to PAL or NTSC and can be set(also in realtime) from 1 to 4Mhz.

Cool Thomas Henry link

For eurorack zorlon cannon and maybe hex invertors Jupiter Storm

Reading the description of the sounds from that link something like the hertz donut mk2 would work as well, seems like the big thing it's doing is fming rather than filtering

If you're looking for something computer-ey, and you have Reaktor, this might be of interest.

YMCK's magical 8bit plug may be able to do it as well.

If you mean modular as in analog modular synth, you could buy a Zorlon Cannon. Or build something on your own. From a quick google, say this or this:

Just add a voltage controllable squarewave generator.

Acoustic Test Signal Generators  have that kind of ability so I guess, Sweepable Noise Generator? Trash80 made a really nice gameboy papu-eque noise generator in his digitek esemble:

lol....right.

Noise spectrum changer, more like?

EDIT: Grey noise is prettiest.

I thought the minute you tune white noise it ceases to be white noise. Pink or brown?

I like the idea of a tuneable white noise generator. It requires a white noise input though...
Little-scale has written some nice stuff about EEPROM music, so I suggest you have a read:

I can imagine using a serial eeprom with 2kbits of storage and a pic chip of sorts to have it spit out your 4-bit+ sample. Cheap as all hell, but may require some work and programming on your end. Once you got that worked out, you could then feed it into your tuner as posted above.

Hm... Thanks for all this feedback, but I suppose a better question to ask would have been: how can I "sweep" the pseudo white noise the same way a gameboy does? Have any of you ever built something modular to do this?
Also is this what I'm looking for? http://www.nutsvolts.com/uploads/magazi … erator.pdf

That's why I've marked I was talking (writing) about abstract categories.

Right! But you've chosen a bit different property, the inability to be random is a nonimmanent consequence of it (and some other properties). I agree about practical details you have mentioned.
